Hi-Therm PEXa2Gen PEXa EVOH 16x2.0 pipe is A three-layer PEXa pipe with EVOH oxygen barrier for underfloor and radiator heating systems.
The EVOH oxygen barrier reduces oxygen diffusion into the heating circuit, helping protect metal components from corrosion and extending system service life.

Installation: installation should be carried out by qualified personnel at an ambient temperature of at least +10°C. Press fittings or compression fittings suitable for 2.0 mm wall thickness are recommended.
Before covering the underfloor heating circuit, hydraulic leak testing must be completed. During screed pouring, the pipe should remain under 0.3 MPa pressure; the minimum screed layer above the pipe is 3 cm.
